java string转为xml
一、使用最原始的javax.xml.parsers,标准的jdk api// 字符串转XML
String xmlStr = \"......\";
StringReader sr = new StringReader(xmlStr);
InputSource is = new InputSource(sr);
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder=factory.newDocumentBuilder();
Document doc = builder.parse(is);
//XML转字符串
TransformerFactory tf = TransformerFactory.newInstance();
Transformer t = tf.newTransformer();
t.setOutputProperty(\"encoding\",\"GB23121\");//解决中文问题,试过用GBK不行
ByteArrayOutputStream bos = new ByteArrayOutputStream();
t.transform(new DOMSource(doc), new StreamResult(bos));
String xmlStr = bos.toString();
这里的XML DOCUMENT为org.w3c.dom.Document
二、使用dom4j后程式变得更简单
// 字符串转XML
String xmlStr = \"......\";
Document document = DocumentHelper.parseText(xmlStr);
// XML转字符串
Document document = ...;
String text = document.asXML();
这里的XML DOCUMENT为org.dom4j.Document
三、使用JDOM
JDOM的处理方式和第一种方法处理很类似
//字符串转XML
String xmlStr = \".....\";
StringReader sr = new StringReader(xmlStr);
InputSource is = new InputSource(sr);
Document doc = (new SAXBuilder()).build(is);
//XML转字符串
Format format = Format.getPrettyFormat();
format.setEncoding(\"gb2312\");//配置xml文档的字符为gb2312,解决中文问题
XMLOutputter xmlout = new XMLOutputter(format);
ByteArrayOutputStream bo = new ByteArrayOutputStream();
xmlout.output(doc,bo);
String xmlStr = bo.toString();
这里的XML DOCUMENT为org.jdom.Document
四、JAVASCRIPT中的处理
//字符串转XML
var xmlStr = \".....\";
var xmlDoc = new ActiveXObject(\"Microsoft.XMLDOM\");
xmlDoc.async=false;
xmlDoc.loadXML(xmlStr);
//能够处理这个xmlDoc了
var name = xmlDoc.selectSingleNode(\"/person/name\");
alert(name.text);
//XML转字符串
var xmlDoc = ......;
var xmlStr = xmlDoc.xml
这里的XML DOCUMENT为javascript版的XMLDOM
